Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb eines Dampfturbinenkraftwerks mit einem mit Braunkohle befeuerten Dampferzeugers, bei welchem die Braunkohle zunächst einer indirekten Trocknung, vorzugsweise in einem Wirbelschichttrockner, unterzogen wird. Der Wirbelschichttrockner wird zumindest teilweise mit Dampf aus dem Wasser-Dampf-Kreislauf des Dampferzeugers beheizt. Das Verfahren gemäß der Erfindung zeichnet sich dadurch aus, dass die Energie des aus der Trocknung der Braunkohle anfallenden Brüdens zumindest teilweise zur Vorwärmung der Verbrennungsluft verwendet wird.The invention relates to a method for operating a steam turbine power plant with a lignite-fired steam generator, in which the brown coal is first subjected to an indirect drying, preferably in a fluidized bed dryer. The fluidized bed dryer is at least partially heated with steam from the water-steam cycle of the steam generator. The method according to the invention is characterized in that the energy of the resulting from the drying of lignite vapor is at least partially used for preheating the combustion air.
